Anti-static and scratch-resistant automobile paint and preparation method thereof

Abstract

The invention discloses anti-static and scratch-resistant automobile paint and a preparation method thereof, and relates to the technical field of automobile paint. Firstly, cyano piperazine, hydroxyphenylacetone aldehyde and bromochlorochalcone are utilized to modify polyurethane, so that the automobile paint can self-repair scratches under ultraviolet light, and the heat resistance of the automobile paint is improved. Secondly, carbon nanotubes are pretreated through laser, silver is deposited on the surfaces of the carbon nanotubes through radio frequency glow discharge, ultrasonic waves and electrostatic field assisted electron beams to obtain a self-made filler, so that the automobile paint has good anti-static property. Thirdly, the self-made filler is treated through ultrasonic waves, and finally the self-made filler, the modified polyurethane and auxiliaries are stirred and mixed to form a conductive network, so that the anti-static property of the automobile paint is improved. The anti-static and scratch-resistant automobile paint prepared by the invention has anti-static, scratch-resistant and high-temperature-resistant effects.

Description

technical field [0001] The invention relates to the technical field of automobile coatings, in particular to an antistatic anti-scratch automobile paint and a preparation method thereof. Background technique [0002] Car paint is the paint sprayed on the car, which can not only play a protective role, but also play a decorative role. The outer layer of modern car paint is also called transparent paint layer, which is only 0.05mm thick. It is glossy and beautiful. It can form a protective layer on the surface of the car body, making the car paint layer not easy to be corroded and scratched, and can prolong the life of the car body. service life. As the car has been exposed to wind and rain all year round, extremely high requirements are placed on the performance of the car paint film as a car paint protection film. Heat and scratch resistance put forward higher requirements. In the prior art, nano-powders are often added to obtain car paint by means of mechanical and physi...

AI Technical Summary

Problems solved by technology

In the prior art, nano-powders are often added to obtain car paint by means of mechanical and physical dispersion, but this method cannot uniformly disperse the nano-powders in the resin matrix, and is easy to agglomerate, resulting in poor scratch resistance; After the paint is scratched, car care agents are often used to fill or replace the car paint, which often increases the burden on the car owner

[0003] In addition, the north is cold and dry in winter, and car owners are often shocked by the static electricity accumulated in the car when driving the door or the car, especially when refueling at the gas station, which may cause accidents. Moreover, static electricity often absorbs a large amount of dust, affecting The car is beautiful, so we invented an anti-static self-repairing scratch car paint to solve the above problems
